Definitions

  • the invention relates to a wishbone as a suspension component of the wheel suspension of a motor vehicle and a method for producing the single-shell shell body for a wishbone.
  • a generic wishbone is part of the stand by DE 200 09 695 U1 of the technique.
  • the wishbone is a hollow steel configuration made of pressed, steel sheets welded together and at least in sections with an inner reinforcement plate that increases the stiffness Mistake.
  • the reinforcement plate is arranged in the plane in which the buckling stresses have an impact.
  • This wishbone has in proven in practice. Compared to solid structures, it is a much cheaper one Behavior achieved under bending and torsion stresses. Although at the wishbone can already be reduced in weight further component optimization appears, also with regard to the weight , desirable.
  • the object of the invention is therefore based on the prior art to create a wishbone with a weight-optimized design has a high rigidity behavior, and a method for its production show.
  • the crux of the invention is the single-shell construction of the wishbone on the legs of the shell body in one piece inwards to the central longitudinal plane Connect directional bars.
  • the shell body To manufacture the shell body, one is on the later contour of the Cross member configuratively adapted metal plate to a bowl-shaped Preform with a bottom and edge-side, protruding from the bottom Legs reshaped.
  • the metal board used is initially flat and points a shape corresponding to the development of the shell body to be produced on.
  • the preform made from it is then in a forming device with inner support of the floor in some areas by means of an inner stamp from an outer die in a hollow shape to the shell body.
  • the free ends of the legs are inward towards Formed the central longitudinal plane of the shell body.
  • the hollow shape has one engraving adapted to the configuration of the shell. Conveniently, the deformation of the legs is limited by stops in the hollow shape.
  • the forming device consequently comprises a three-part press tool, which consists of the inner stamp and the outer stamp as well as the hollow form consists.
  • the control arm according to the invention has high rigidity. This is provided by the inward side ridges on the legs guaranteed.
  • the contour and geometry the web is adapted to the required bending and torsional rigidity as well as the buckling stiffness.
  • On a double-shell version of the Wishbones or the use of reinforcing plates is according to the invention deliberately waived. This allows the weight of the wishbone to be increased again be significantly reduced.
  • the wishbone contributes to an improvement in the suspension Directional stability and strengthens the stability of an axle, especially a front axle.
  • the wishbone thus contributes to passive safety of a vehicle as well as to improve sporty driving behavior.
  • the web is advantageously wider on the inner circumference of the arc section dimensioned as at its ends (claim 2). This measure contributes to the increase the bending stiffness in the arch section and increases the bending and torsional strength the wishbone.
  • the ends of the legs run obliquely to the floor at the longitudinal sections lowered (claim 3).
  • Claim 4 provided in the direction of the legs passages.
  • the Passages are used to hold a ball joint or a rubber bearing.
  • the outer radius of the ends of the legs is concentric with the passages, the legs here over the entire outer circumference in a small amount Distance to the collar of the passages.
  • the floor in the arch section with a passage in the direction of the legs has a circumferential collar.
  • This passage also forms a recording for an add-on unit, especially the shock absorber.
  • the load-oriented design of the stiffness behavior can be influenced are embossed in the bottom of the shell body, as this claim 6 provides.
  • the dimension and position of the embossing is coordinated to the respective embodiment of the wishbone.
  • FIGS 1 and 2 show a wishbone 1 according to the invention
  • Control arm 1 comes within the wheel guide or the wheel suspension of a motor vehicle for use.
  • Two so-called triangular wishbones are available.
  • the upper wishbone is connected to the body via rubber bearings.
  • the lower wishbone is attached to the axle beam. Both wishbones run over ball joints the steering knuckle.
  • Coil springs and gas pressure shock absorbers are separate arranged from each other on the lower wishbone.
  • the control arm 1 has an L-shaped configured shell body 2 Sheet metal on with two longitudinal sections 3, 4 and one between the Longitudinal sections 3, 4 located arc section 5.
  • a receptacle in the form of a Passage 7 for a ball joint 8 (see Figure 1) is provided.
  • the end 9 of Longitudinal section 4 is also formed with a passage 10 Provided for a rubber bearing 11.
  • the shell body 2 has a base 12 with legs 13, 14 on the edge, 15 on.
  • the legs 13, 14, 15 are aligned at right angles to the floor 12.
  • At the legs 13, 14, 15 also close at right angles to the inside Center longitudinal plane ML of the shell body 2 directed webs 16, 17, 18 in one piece on. It can be seen that the web 16 on the inner circumference of the arc section 5 is dimensioned wider than at its ends 19, 20.
  • the legs 13, 14, 15 extend at the ends to the ends 6 and 9 of the longitudinal sections 3 and 4, respectively lowered obliquely to the bottom 12 of the shell body 2.
  • An extension 21 is provided on the outer circumference of the arc section 5, which forms a bearing connection 23 at its free end 22.
  • a bearing connection 23 at its free end 22.
  • the legs 14, 15 are free End 22 of the extension 21 is semicircular and conforms to the contour of the sleeve 24 adjusted.
  • the bottom 12 in the arch section 5 one to the Legs 13, 14, 15 pass-through 26 issued in the same direction encircling collar 27.
  • the bottom 12 of the shell body 2 is in Longitudinal section 4 provided with an impression 28.
  • the impression 28 carries to increase the rigidity of the wishbone 1.
  • FIG. 3 schematically shows a forming device for producing the Shell body 2 for a wishbone 1. To manufacture it first an initially flat metal plate to form a bowl-shaped preform 30 reshaped. Such a preform 30 is shown in simplified form in FIG. 3. The metal board used corresponds to the level processing of the one to be manufactured Shell body 2.
  • the forming device 29 comprises an outer stamp 31, an inner stamp 32 and a one- or multi-part hollow mold 33.
  • the preform 30 is in the shaping device 29 inserted and then under some areas inside Support of the bottom 12 by means of the inner punch 32
  • Outer punch 31 in the hollow form 33 is finally formed, the free ends 34, 35 of the legs 13 and 14 inwards towards the central longitudinal plane ML of the Shell body 2 to the webs 16 and 17 are formed.
  • the end position the webs 16 and 17 are limited by stops 36, 37 of the hollow shape.
  • Figure 3 shows the shell body 2 in a vertical sectional view according to the line A-A in Figures 1 and 2.
  • the contour of the outer stamp 31 and the inner punch 32 is the geometry of the shell body with the Embossing 28 is shaped accordingly in this area.
